Z-Ser-Gln-OtBu is a tripeptide, a chain of three amino acids, consisting of serine (Ser), glutamine (Gln), and a terminal ot-butyl (OtBu) group. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids and the protective group are important in the field of biochemistry and pharmaceuticals, as they can be used to study protein structure, function, and interactions, as well as in the development of new drugs and therapeutics.
The CAS Registry Mumber 89375-60-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,7 and 5 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 89375-60: (7*8)+(6*9)+(5*3)+(4*7)+(3*5)+(2*6)+(1*0)=180 180 % 10 = 0 So 89375-60-0 is a valid CAS Registry Number.
